Adafruit CLUE - nRF52840 Express with Bluetooth LE

Do you feel like you just don't have a CLUE? Well, we can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board.

The Adafruit CLUE features a small high-resolution 1.3" 240x240 color IPS TFT display and is packed with sensors, compatible in shape and size with the BBC micro:bit, and designed to fit your existing robot kit or 'bit add-on with the same edge connector.

• Nordic nRF52840 Bluetooth® LE processor – 1 MB Flash, 256 KB RAM, 64 MHz Cortex M4 processor
• 1.3" 240×240 Color IPS TFT display for high resolution text and graphics
• Power from any 3-6V battery source with internal regulator and protection diodes
• Two A/B user buttons and one reset button
• Tons of sensors including:
  • ST Micro series 9-DoF motion sensors: LSM6DS3TR accelerometer/gyroscope and LIS3MDL magnetometer
  • APDS9960 Proximity, Light, Color, and Gesture Sensor
  • PDM Microphone sound sensor
  • SHT Humidity sensor
  • BMP280 temperature and barometric pressure/altitude sensor
• RGB NeoPixel indicator LED
• 2 MB internal flash storage for datalogging, images, fonts or CircuitPython code
• Hardware SPI, UART, I2C, and I2S on any pins
• Buzzer/speaker for playing tones and beeps
• Two bright white LEDs in front for illumination or color sensing
• Qwiic / STEMMA QT connector for adding sensors, motor controllers, or displays via I2C
• Programmable with Arduino IDE or CircuitPython

Please note there is currently no MakeCode or Scratch support for the nRF52840 chipset. The CLUE is specially tailored for projects that use multiple sensors and need Bluetooth data transfer or logging capabilities.
